hi all,
we are looking for best motion capture systems can capture good data from human and animal …
anybody know about best optical motion capture systems in market , link and prices ?
also i have same question about human wireless mocapsystem?
thank you.
I bought a Gypsy Gyro 18 last week. It’s great as the data is very clean indeed and it takes only about 15 mins to unpack and get up and running. Plus you can use it anywhere. even outside.
The main problem, (which is not hard to overcome) is that it works out root translation by the foot placement. Hence… if you jump, it will appear that the character is squatting down so you will need to reverse the downward curve of the root to an upward one. It’s pretty easy to do.
Obviously the Gypsy Gyro 18 only works with humans… and it’s expensive.
If you can afford it…go for a Vicon setup. A basic 6-8 MX cameras will do the trick , accompanied with their IQ software. What about your capture space/volume? An optical rig can take up alot of space, especially if you intend on capturing animals. This too can be expensive.
thank all for answer
i search for this spacifictions :
1-capture 2 or 3 person in real time.
2-low noise in data captured.
3-my volume is about 8 m * 8 m
any body have vicon mx3 .3megapixel ?
are this camera have huge noise in small or big volume or in 2 - 3 person capturing?
if you have any knowlege about this camera please talk about it?
I randomly bumped into these guys at Siggraph.
Their demo movie is spiffy, but what do I know, I’m a shader guy

[color=white]Check out www.phasespace.com. They use active led markers and no suits. Plus their equipment can be run with one operator at about 1/3 the cost, generates 480 f/s and pretty well eliminates occlusions and dropouts. Also, their markers can be attached to with lycra suits or stuck on the subject in some other way, so impeedment of movement shouldn’t be a problem.

It appears that on each tripod is atleast 2 cameras. they place a tripod at each corner of the capture area. thus you actually have an 8 camera system with a 4 point system. Kinda nifty.
www.naturalmotion.com will have a motion capture system in August for under 5,000 dollars!
some of the raw data I’ve tested with was pretty good!
are you sure you don’t mean http://www.naturalpoint.com/ ?
the sample data I’ve seen was good but not comparable in quality to that which I’ve captured with a vicon system. Still, big price difference…

I’d love to see how good the dirty data is using a Vicon system. I wonder how much cleanup it really takes? And how many mocap places in teh UK. Seems like everyone has one. Can I fly up and use it?
True, but we’re talking $5,000 versus $250,000. Plus you can do a lot with filtering.
Brother man we need to talk about MOCAP in depth. I know you had some luck making your animation with it.
The data quality is as dependent on the number, frame rate and resolution of cameras and the volume you’re capturing as the actual system itself so really it’s hard to say that system X is better than system Y without taking into account the other factors. My impression of the optitrack data was that the marker positioning was quite low resolution and I wondered how many cameras you’d need to cover a reasonable volume at a decent level of quality compared to a higher end setup like vicon or motion analysis.
True, you can do an amount of cleanup with filtering but the more you do, the more you can lose the nuances that make the mocap what it is. Filtering can reduce spikes and steps in the curves but it can’t increase accuracy so if that’s what you’re after then it can be counterproductive to filter everything.
Regarding some of the other systems out there, the xsens looks promising for an inertial suit and the data looks better than the gypsy gyro but still doesnt have the accuracy of an optical system. It’s also still quite a bit more expensive than the optitrack will be.
Incidentally, you might have seen that vicon are advertising the FK extreme package as a ‘budget’ mocap system for £26,000 ($50,000?). I called vicon to find out more about it but the guy I spoke to wasn’t exactly enthusiastic and was keener to push the advantages of a more expensive system. It’s a bit of a confusing tactic so I wondered if it’s just a way of getting people to make contact who otherwise would have been put off by the high price tag.
That’s hilarious, I like when they say “budget” or “lowest cost” The thing is why is motion capture so expensive these days.
50,000 USD is enough to buy a house in parts of the US and a fancy Mercedes or luxury car. It’s funny considering the cameras are simply cameras that pick up color differances dots vs no dots.
Alot of the current MOCAP is not exactly new technology. The basic components of the Gypsy Gyro and the Moven system can be found in a WII Nintendo.
I wonder if someone could program a program that let’s you put WII controllers on you and make a makeshift MOCAP. That would be cool.
I think it is good that there is a system coming out for under 5,000 dollars because then someone else will do it and then more and more people will be forced to pull the price tag down.
It’s getting to where normal cameras will be used to do motion capture with specialized software recognizing the human body. What will some of these companies do then?
MOCAP is an interesting thing to watch as it is becoming more popular with top Hollywood, I’m sure we will be seeing MOCAP systems go down as these are becoming more common place.
We’ll see what htis little MOCAP system will do coming soon.
there already are systems that use video cameras for motion tracking, vicon do one and there’s also a new one from organic motion that looks interesting, if a little limited at the moment
As far as the pricing goes, if you’re talking about the base cost of buying the kit itself then yes, it’ll probably come down as the high end of this year becomes next years mid performance system. If you’re talking about going to a mocap studio to do some capture then they have a whole bunch of costs besides the capital outlay on equipment; staff, studio space, utilities, maintenance and so on which need to be covered. For this market the real killer would be if someone came out with a system that was so easy to use and cheap enough to buy that it’s more cost effective to do that than pay for a session at studio.
My guess is that companies like vicon are unlikely to attempt do this seriously as their market is at the ‘high end’ - film studios, sports labs etc so it’s more likely that a company who don’t have an interest in maintaining that end of the market will attempt to bring out a real ‘budget’ system.
I bought a moven suit a couple of months ago. While the investment is quite heavy its been totally worth it. Im now seeing my business going from typical tv-show intros with flying logos and all that stuff to alot of much more exciting projects based on motion capture. Moven is the first system I´ve seen that hasn´t had any particular constraints. While you can reach 100m in range, you could cover alot larger areas if you want to. Also its alot easier to rentout Moven than a full sized optical studio
I know Syndicate (small visual FX studio) also bought a Moven system (www.moven.com)
their description of the system: http://www.syndicate.se/default.aspx?idStructure=2213))
Surprising to see what cool stuff they did in such a short time…they got a commercial featuring mocap from Moven (of a hamster!) on German TV 
Personally, after seeing some results and seeing it in action, I’ve become a big fan of Moven.
As the CTO of XSENS said at EUE, “You could mocap a marathon, if you just could persuade someone to take the laptop on a bike and keep it within the wireless range the whole time”.
Also the fact you can slap it under normal clothes (or any clothes) is fantastic. Think how much easier “Pirates” would have been to do if they didn’t have to paint out all those dorky gray pyjamas all the time, but could put the actors in rough costumes that might actually be (partially) useful, or at least would cast proper bounce light and reflections around on nearby surfaces!
The fact that you can trivally rent out the suit when you are not using it with very little hassle is just extra icing on the cake.
